I was able to change the ranking of my issue for month.
And since 2 weeks, I can't modify ranking.
I drag & drop my issue in greenhopper UI. The ranking there is OK but if I refresh my page i've got my old ranking.
I try to optimize the rank => No change
I try to filter my context => No change.
For information I've got +4000 issues in my project.
Someone can help me ?
